About OpenDDD

Open Domain-Driven Design — Open Domains, Open Knowledge

What is OpenDDD?

OpenDDD (Open Domain-Driven Design & Agentic Platform) is an open domain-driven design and agentic platform.

Core philosophy: Every domain deserves to be open, every piece of knowledge deserves to be reused.

Open = Open knowledge boundaries
DDD  = Domain-driven design methodology
Agentic = AI agent empowerment
Platform = Reusable knowledge platform

Why "Open Domains"?

In traditional development, domain knowledge exists implicitly in code and people's minds, lost as people move on. OpenDDD advocates:

Traditional	Open Domains
Domain knowledge → Implicit	Domain knowledge → Explicit modeling
Experience leaves with people	Experience structured and preserved
Start from scratch every time	Cross-project free reuse
Closed evolution	Open shared improvement

Three Pillars

1. Domain-Driven Design (DDD)

• Clear bounded contexts, aggregate roots, domain events
• 5-layer Clean Architecture
• Serverless-first deployment architecture

2. Agentic Integration

• Unified access to Kozi, GPTs, Claude and other AI platforms
• Multi-agent collaboration system
• Cognitive engine + memory system

3. Knowledge Sharing (Open)

• Skill prompt library — replace variables and use immediately
• Workflow templates — composable multi-step processes
• Learning roadmaps — learn-by-doing growth paths
• Practical recipes — ready-to-use complete solutions
